## ProcureMaster

ProcureMaster attacks a specific bottleneck in cross-border sourcing: the flood of new supplier inquiries that a single buyer can face each day. Traditional workflows mean manually opening supplier pages, sending the same introductory questions again and again, and retyping answers into spreadsheets. ProcureMaster turns that repetitive first round into an automated step.

The extension works on 1688.com, a major Chinese wholesale marketplace. A buyer defines what they want — the product, the quantity, and the price target — and the tool uses natural-language processing to engage suppliers in a preliminary negotiation, mimicking how an experienced buyer would open a conversation. When the exchange is done, the results are compiled into a structured procurement report so the buyer can compare options and decide quickly.

The value proposition is time. By handling the first, most repetitive layer of supplier outreach automatically, ProcureMaster lets procurement staff focus on evaluating offers and closing deals rather than copying and pasting messages. It is a focused, niche tool with a small but real user base, and it is best suited to teams whose sourcing is concentrated on 1688.com and cross-border purchasing.

**Pricing & Plans:** ProcureMaster is distributed free to add as a Chrome Web Store extension; the store lists it as free with no in-store price. For larger sourcing needs or enterprise arrangements, contact the developer directly.

- **Custom procurement tasks:** Create a purchasing task by defining the target price, target quantity, and target product so the extension knows exactly what to negotiate.
- **Automated negotiation:** Natural-language processing lets the extension simulate an experienced buyer and hold effective online negotiations with suppliers on your behalf.
- **Structured procurement reports:** After negotiation, collected supplier information is organized into an easy-to-read structured procurement report for faster decision-making.
- **Time savings for buyers:** Frees buyers from repetitive first-round outreach, shortening procurement cycles and cutting manual busywork.
- **Built for 1688.com sourcing:** Purpose-built for sourcing on 1688.com and handling large volumes of cross-border supplier inquiries.

**Strengths:** Automates the repetitive first round of supplier outreach and negotiation; Turns scattered supplier replies into a structured, comparable procurement report; Purpose-built for 1688.com sourcing workflows and cross-border buyers; Lightweight Chrome extension that plugs into the browser you already use

**Limitations:** Very small user base, which limits community feedback and shared best practices; Interface and product copy are primarily in Chinese, so non-Chinese buyers may find it harder to use; Automated negotiation quality depends on how well supplier listings are structured; Focused on 1688.com, so it is not a fit for sourcing on other marketplaces

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
